This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

4 findings rated critical or high. Fix these first.

  1. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  2. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

  3. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • High

      Weak SPF Policy

      SPF record has permissive policy allowing any server to send email

      What to do: Use -all or ~all qualifier for better email security

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

Diffuse operates as a niche digital agency focusing on creative development services for businesses. Their portfolio includes projects built on Shopify, Wordpress, and custom Next.js solutions, indicating a flexible and modern approach to client needs. The business model is service-oriented, targeting small to medium enterprises requiring bespoke digital solutions. The company leverages partnerships with platforms like Shopify and Wordpress but does not publicly disclose parent or subsidiary relationships. The presence of cookie consent and privacy policy pages suggests awareness of compliance requirements. Growth potential is indicated by a diverse project portfolio and use of advanced technologies. However, the lack of explicit contact information and security policies may limit trust for some clients.

Security posture

The website demonstrates a moderate to good security posture with HTTPS enforced and cookie consent mechanisms in place. However, the absence of key security headers such as Content-Security-Policy and X-Frame-Options reduces defense-in-depth. No incident response or security policy pages are published, and no dedicated security contact channels are provided. The use of third-party scripts like Google Tag Manager introduces potential risk vectors that require regular auditing. No vulnerabilities or exposed sensitive data were detected in the HTML content. Overall, the security maturity is adequate for a small agency but could be enhanced by adopting best practices and transparency measures.

Recommendations

  1. Implement and enforce security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to improve protection against common web attacks.
  2. Publish a dedicated security policy and incident response page with clear contact information for reporting vulnerabilities or incidents.
  3. Enhance transparency by providing verified company contact details such as email and phone numbers on the website.
  4. Regularly audit and update third-party scripts and dependencies to mitigate risks from vulnerable libraries.
  5. Consider adding trust signals such as certifications, client testimonials, or awards to strengthen business credibility.

Notes

The website is built on a modern technology stack featuring Next.js and React frameworks, with integrations to Wordpress, Shopify, and Payload CMS platforms.

Performance is moderate with good mobile responsiveness and SEO optimization. Accessibility features are basic but present. The use of privacy-protected WHOIS data is common for small agencies but limits transparency. Hosting provider details are not disclosed. Overall, the technical implementation supports a professional and scalable digital presence with opportunities to improve security and accessibility.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
